Panduit EV18-10RB-Q 22-18 AWG Ring Terminal

Panduit EV18-10RB-Q StrongHold™ Insulated Ring Terminal

The Panduit EV18-10RB-Q is a vinyl-insulated ring terminal engineered for 22–18 AWG stranded copper wire terminating to #10 (M5) screw studs. Part of Panduit's StrongHold™ series, this connector is spec'd for commercial and industrial installations where UL/CSA compliance, vibration resistance, and long-term reliability matter—battery terminations, UPS installations, access control power distribution, and rack PDU connections. The butted-seam barrel design and funnel-entry wire insertion reduce crimp-induced strand damage compared to overlapped-seam economy terminals. Packaged in 25-piece quantities for project-based purchasing.

Key Features

• 22–18 AWG wire range – accepts 0.5–1.0 mm² stranded copper; funnel entry guides wire into barrel without strand fray
• #10 screw stud (M5 metric) – 0.31" tongue width fits standard M5 or 10-32 terminal blocks, breakers, and PDU posts
• Red vinyl insulation – color-codes 22–18 AWG per industry convention; 600V rating; resists moisture and abrasion in dusty/damp environments
• Zinc-plated copper barrel – corrosion-resistant finish maintains conductivity in telecom closets, battery rooms, and outdoor-rated enclosures
• UL 587-H listed, CSA certified – meets NEC and CEC requirements for commercial power terminations; flame rating UL 587-H for plenum-adjacent wire runs
• Compatible with Panduit CT-series crimp tools – CT-100A, CT-600-A, CT-1550, CT-1551, CT-2500, CT-160, CT-260, CT-402 (see tool nest size for 22–18 AWG)
• Butted-seam barrel – edges meet without overlap, reducing stress concentrations during crimping and minimizing barrel splits under vibration
• 25-piece package – project quantity; master cartons of 250 available for large-scale installations

The EV18-10RB-Q uses a butted-seam copper barrel with electrolytic zinc plating, offering better corrosion resistance than bare copper or tin-dipped terminals in battery rooms and telecom vaults where sulfur compounds and humidity accelerate oxidation. The vinyl insulation is rated to 600V and resists common solvents, UV exposure (indoor), and flexing during wire dress—critical when routing cables with tight bend radii around DIN rail terminals or into crowded PDU blocks. The funnel-entry barrel mouth guides 22–18 AWG stranded wire (7-strand or 19-strand) into the crimp zone without splaying individual strands, a failure mode that reduces contact area and increases resistance over time. Properly crimped with a calibrated ratcheting tool (Panduit CT-series or equivalent), the terminal achieves a gas-tight cold-weld between barrel and conductor, maintaining <1 mΩ contact resistance at rated current. The #10 tongue (0.31" wide, 0.191" hole diameter) mates with M5 metric studs (common on European-spec PDUs and breakers) or 10-32 UNC studs (North American standard), covering both markets without adapter hardware. The 0.94" overall length and 0.31" tongue width clear most recessed terminal blocks and allow stacking of two terminals per stud when code permits.

StrongHold™ terminals are engineered for commercial integrators running power to access control panels, PoE mid-span injectors, UPS battery strings, and rack-mount PDUs—installations where a failed crimp costs truck rolls and downtime, not just a $2 part. You'll find EV18-10RB-Q ring terminals terminating 18 AWG power feeds into DMP XR-series panels, connecting 20A branch circuits to APC Smart-UPS battery packs, and landing 18 AWG ground wires at rack grounding bars in data centers. The red insulation color-codes 22–18 AWG per ANSI/NECA standards, letting inspectors and maintenance techs verify wire gauge at a glance without stripping insulation. The UL 587-H flammability rating qualifies the terminal for wire runs adjacent to plenum spaces (though the wire itself must be rated accordingly), a common requirement in drop-ceiling telecom rooms where fire code restricts non-rated components. For vibration-prone environments—industrial access gates, outdoor PTZ camera power feeds on poles, moving machinery enclosures—the butted-seam barrel resists fatigue cracking better than overlapped-seam designs, which concentrate stress at the seam edge and can split after thermal cycling or mechanical shock.

Panduit's StrongHold™ line is the go-to for integrators who need terminals that pass NEC 110.14 torque specs and hold up under AHJ inspection—UL/CSA dual-listing, precise dimensional tolerances for automated crimp tooling, and lot traceability for mission-critical projects. The EV18-10RB-Q ships in 25-piece bags for small jobs (a single controller install, a UPS retrofit) and 250-piece cartons for building-wide deployments, giving you project flexibility without overbuying commodity consumables.
